NCCO Technology involves the use of ‘contained’ ozone in combination with zeolites (crystalline solids with uniformly-sized, nano-scale pores) and other related porous materials. In contrast to ozone generators, which directly release the toxic gas into the environment and are known to be ineffective, NCCO greatly enhances the oxidation of contaminants while avoiding high emission of ozone and harmful reaction intermediates. The zeolites consist of a negatively-charged aluminosilicate framework with loosely bound cations that maintain the charge balance. A number of natural and synthetic zeolites with varying chemical compositions have been exploited for different commercial applications. Zeolite filters can be used in air purification for the adsorption of gaseous pollutants Interestingly, zeolites also have the ability to catalyze diverse reactions inside the nanosized pores . NCCO is based on a catalytic ozonisation mechanism where ozone (O3) provided by an upstream ozone generator is decomposed into molecular oxygen (O2) and active atomic oxygen (O*) at acidic sites of the adsorbent. Gaseous pollutants e.g. VOCs that are adsorbed in the same pore as O* undergo catalytic oxidation within the confined nano-cavity. Previous studies show that reaction intermediates remain in the adsorbent, while the smaller final products (such as carbon dioxide and water) are generally released to regenerate the catalyst. Based on the catalytic process, the life of the NCCO Reactor filter has an extremely long functioning and performance life.
